Can't export mp3

I have been use cubase 6.5 with Mac for years, it works well,
today when I want to export to mp3, it said “No more encordings” for no reason, i have no any idea what I did, actually i think i didn’t do anything, and it ask me “go to online shop”, and I did, and install mp3 encoding update …
it still not working. I have removed cubase and reinstall it twice, and it still have same problem…
what should I do???


Please go to and download and install the latest version of the eLicenser Control Center. Next connect your USB-eLicenser key for Cubase 6.5 directly to a different USB port on your computer and open the Cubase 6.5 program, open your project file, and go to File, Export, Audio Mixdown, and tell me of you have an “MPEG-1 Layer 3” option, select it, and see if you are still given the same error message.

Thank you.
